  • Publication number: 20070239152
    Abstract: The electrolytic depilation device works by electrical contact with the skin of an individual whose hair is to be treated by electrolysis. It comprises a case containing an electrical power supply source, an electronic control circuit connected to the electrical power supply source for supplying a first electrode and a second electrode of different polarity. The electrodes are located at a distance from one another to apply a current that initiates electrolysis at the level of the hairs to be treated. At least the first electrode is elongated and located on one of the ends of the case so as to be applied against the skin over its entire length. The electrode has a shape that is convex in cross section.
